In this article a simple and rational technique is described to make a complete denture. This technique is based upon the utilization of the articulator as an instrument necessary to the realization of the final prosthesis and as an intermediary between the general practitioner and the laboratory technician. As the physiology rules the determinants of the occlusion, the mandibular kinetics determines the orientation of posterior teeth. This way, step by step, the physiological recording of the condylar pathway, of the anterior guidance and of the level of the plane of occlusion will enable the laboratory to realize a set-up of the prosthetic teeth to conform with the esthetic criterias.
Although the anterior guidance in complete dentures is not really a guide, the arrangement of the anterior maxillary and mandibular prosthetic teeth, defines a propulsive line called the virtual anterior guidance, a part from the cinematic criterias. The influence of this guide on cuspal movement is superior, in all mandibular points, to the influence of the condylar pathway. If this line is not respected, the practitioner may have to do excessive grindings during occlusal adjustments.
